Born Robert Velline in Fargo, North Dakota, Bobby was just 15 when he took to the stage in nearby Moorhead, Minnesota, to fill in after the 1959 plane crash that killed Buddy Holly, Ritchie Valens and JP "The Big Bopper" Richardson.

Within months, Bobby and his band, The Shadows, had a regional hit with Suzie Baby. He went on to record 38 Top 100 hits.

He also gave a young Bob Dylan his start.

Bob played briefly with Bobby's band and suggested he change his last name to Vee.
